I've been marching along for the past months without any issue and suddenly I can't enter debug. It's as if it's being held in reset or something.If I remove the debugger, it sometimes starts up the firmware (I have a light that lights). I have tried both my development kit and my PCB. This was working fine. Also I am suddenly getting this dialog box that keeps popping up when I 'save' or when I try to debug. It flashes 2-4 times and is title 'Windows Updating'...
